SPECIFICATION forming part of Letters Patent No. 297,701, dated April 29, 1884.

Application tiled March 21, 15.584. (No model.)

To all whom t may concern.-

Beit known that I, DAVID T. LINEGAR, a citizen of the United States, residing at Cairo, Alexander county,lllinois, have invented certain Improvements in Car-Couplings, ofwhich the -following is a specification.

My invention relates to that class of couplings in which the cars are coupled by means of links and pins passing through vertical openings in the draw-heads; and the Inain object is to provide a simple, cheap labor and life saving attachment which canV be applied to the car-couplings now in common use, especially those of the i'reightcar pattern, to render the coupling ot' the cars automatic. This object l". attain as more fully described hereinafter. A

In the accompanying drawings, FigureV 1 is a view or side elevation of a draw-head with my improved pin-support applied thereto.

Fig. 2 is a similar View with the pin-support pushed back and the link and pin shown in coupled position. Fig. Sis a side elevation of a common draw head without my appliance. Fig. 4 is a sectional elevation, the supporting-head and telescopic tube with inclosed springs.

A is the supporting-head, upon which the pin rests; B, tube attached to head; C, tube att-ached to lilling-pieceE; D, the spiral springs.

F is the open space in the common draw-head. My invention may be applied to any of the draw-heads now in common use,castorwrought iron, by aslight change in the supportinghead A to suit the draw-head to which it is to be applied. The drawings, however, are taken from the wrought-iron draw-heads in common use, and the links and pins are the saine as those in common use, and will couple cars when the draw-heads are of different heights, as is now done by hand. Y

My attachment, as :illustrated detached in Fig. 4. consists of the supporting-head or pin rest and support A; B, tube attached to head; C, tube attached to filling-piece E, and D the spiral spring, ,and when in position are oper-` ated as shown in Figs. l and 2.

I claim as my invention- The combination, with the draw-head, of the pin rest and link-supporting head A, tube B attached to head, tube C, attached to fillingpiece E, and the spiral spring D, as shown anddescribed.

DAVID fr. LINEGAR.
